To all whom 'it may concern:

Be it known that we, EDMUND H. LUNKEN and HENRY RITTER, citizens of the United` States, residing at Cincinnati, Ohio, have invented certain new and useful Improvements in Window Construction, of which the following is a specification.

Our present invention relates to improvev ments 1n window construction and 1s designed as an im rovement upon the form'of window which orms the sub]ect of an application for Letters Patent of the Umted States, filed on the 8th of February, 1908 by Edmund H. Lunken and Charles M. Conklin; serial No. 415,446.

Among the objects of the present invention are toimprove the window in various details or features of construction with a view to increased sim licity and durability and economy. in manu acture.

The invention includes the features of construction and arrangement and combination of arts hereinafter described and particular set forth in the appended claims.

T e invention is illustrated in the accompanying drawings, in which Flgure 1 is a front elevation of the improved window. FigQ is a transverse section on line 2-2 of ig. 1, but on a larger scale. Figs. 3 and 4 are enlarged sectional elevations showing more in. detail the manner of'suppor'ting the guide bar and illustrating also the guide bar in its two different positions. Fig. 5 is a transverse sectional view showin the invention as embodied in a wooden win ow casing.

Referring by reference characters to this drawing, the numeral 1 designates the window frame or casing and 2 the window sashes. Each side of the window frame'is provided with two outer channels 3 and a central or intermediate channel 4 these chany nels being formed as integral parts, by press` ingorA stamping, 1n the removable cover or ,facing plate 1 of the frame or casing.

The sashes are supported by sash cords 5 designed to be counterbalanced by wei hts 6 in the usual manner and as the counter alancing'forms no part of the present invention, amore specific descri tion thereof is deemed unnecessary. It su `ces to say that the sash cords are connected to eye leces 7 in which are journaled the hinge plntles 8 upon which the sash frames hinge or pivot, the eye pieces moving vertically 1n the channels 3 as the sashes are raised and lowered. The means for guiding the sashes in their vertical sliding movement comprises bars 9 which are located on opposite sides of the window frame `and are provided with ribs or flanges 9 and 9", which are adapted to enga e with correspondin grooves or channe s in the side edges of t e u per and lower sash respectively. These gui e bars or members extend continuous] and unbroken from the bottom of the win ow frame to the top and form an unbroken guide for the sashes. Each guide bar is referabl constructed of non-corrosive meta stampe or pressed into the desiredshape. The walls which form the ribs 9 and 9" are parallel with a space between in which snugly fit the thin intervening webs 1. between the channels 3 and 4, which webs are formed by the folding or doubling of the metal of the cover plate in the rocess of manufacture of the same. The gui e bars normally dproject'into the position shown in Figs. 2 an 3, and in such position serve to gulde the sashes in their vertical movement and of course prevent their being swung upon the hinge pintles 8. When it is desired to swing either of the sashes for the purposes of cleaning or ventilation, the guide ars are moved laterally away from the sash to remove the ribs 9 and 9h from enga ement with the grooves or channels in the e ges of the sash.

We prefer to construct and arrange the guide bars so that they will be automatically eld by gravity in engagement with the sashesso t at they can be removed from enga ement therewith by simply lifting them an imparting a slight latera swing to the lower ends w iereby they will be automatically locked in their elevated and disengaged position by gravity. To accomplish this a reinforcin bar 10 is provided which is secured to t e portion 9 of the uide bar between the guide ribs. This reinforcing bar is preferab ymade of solid metal and serves to stren then or stiifen the guide bar, enabling te latter to be made of a minimum amount of comparativel thin non-corrosive metal. Each guide bar 1s provided near the top of the window frame with an inclined slot 11 through which passes a pin or rivet 12, which has its ends seated in and held by the walls of the channel 4. In each uide bar near the lower part of the window rame is formed an L or elbow shaped slot 13,

which is engaged by a pin or rivet 14 held iii the manner similar to that described in connection with the pin 12. While we prefer to have the slots in the reinforcing bar and the pins secured to the webs of the casing, it is evident that the construction may be reversed, by placing the slots in the webs of the casing and securing the pins in the reinforcing bars and thereby attain the saine results.

Normally the guide bar and its reinforcing bur will occupy the position shown in l `ig. 3, in which the pins 12 and 14 will rest in the upper ends of the slots 11 and 13 respectively, being so held by the weight of the bar, the inclination of the slot 11 at the upper end causing the bar to be pressed oiitwardly. When, however, it is desired. to move the bar inwardly to diseiigage the bar from the window sash oi sashes to permit the same to be swung upon their horizontal pivots, it is only necessary to raise the guide bar until the pin 14 has reached the bottom of the vertical portion of the L or elbow shaped slot. During this movement the engagement of the pin 12 with the inclined slot ll `will cause the upper end to move laterally and the lower end may be swung horizon tally outward and cause the pin14 to rest iii a horizontal .portion of the L or elbow shaped slot, at which time the uide bar will be locked in its elevated an disengaged osition by gravity. The lower L or e bow shaped slot 13 in each bar is preferably formed by simply cutting in to the rear side of the bar, while the upper slot 11 is formed by cutting in from the front side of the bar, both slots thus opening the one to the front side of the bar and the other to the rear side. In order to hold `the pin 14 in the L or elbow shaped slot 13, a strap 15 of sheet metal is applied over the back of the slot, its ends being secured to the reinforcin bar in any desired manner. The lower en s of the re inforcing bars are inclined as shown to correspond with the inclination of the slot 1i to the.wooden window casin l" by the beads and the space at each end formed by this inclination is filled by blocks or filling members 16.

In Fig. 5 we have shown how the same construction of. guide bar could be applied to an ordinary wooden window frame. In this construction the cover plate 1" is secured or strips A and B and if desired, one edge of this plate maybe turned u as indicated at b and seated in a groove in the strip B for foi-min a more secure engagement.

Having t us described our invention, what we claim isz- 1. In combination, a window casing, re movable cover plates for the sides thereof having two side channels and an intermediate channel with intervening webs separating said channels, a guide bar having parts embracing said webs, a reinforcing bar secured to the rear face of the guide bar between said embracing parts, and a` window sash or sashes guided by said guide bars and having hinge pintles engaging the side channels, siibstantiiilly as described.

2. In combination, a Window frame a cover or facing plate on each side, having a pair of vertical side channels and an intermediate channel, u per and lower sashes having hinge pint es engaging said side channels, guide bars having guide ribs engaging said sashes, a reinforcing bar secured to the rear face of the guide bar, said reinforcing bar having an inclined slot at its upper end and an L or elbow shaped slot at itsl lower end and pins carried by the cover plate and engaging said slots, substantially as described.

3. ln combination, a window frame having in each side member a pair of channels, upper and lower sashes having hinged pintles fuided in said channels, guide bars locate between said channels and extendin the full height of the window casing an having tongue and groove engagement with said sashes, an inclined slot and pin connection between the upper end of each bar and the casing, and an L or elbow shaped Islot and pin connection between the lower end of each rai' and the casing, substantially as described.

4. In combination, a window frame, upper and lower sliding and Swingin sashes having hinge intles guided by sai frame, sheet metal gui e bars having a tongue and groove connection with both said sashes, reinforcing bars secured to the outside faces of said sheet metal ide bars, and means for inovably connecting said reinforcing bars to the window casing, substantially as described.

5. In combination, a window frame havthe upper end of the guide bar upward and outward, and a device simultaneously operating at the lower end of the guide bar, whereby the guide bar when lifted upward and outward at its lower end, is held in such position by force of gravity, substantially as described.

In testimony whereof, we affix our signatures in presence of two witnesses.
